When we dump the CPU registers, there's a certain chance they haven't been synchronized with KVM yet, so we have to manually trigger that. This aligns the code with x86 and fixes a bug where the register state was bogus on invalid/unknown kvm exit reasons.

In kvm-all.c we store an ioctl cmd number in the irqchip_inject_ioctl field of KVMState, which has type 'int'. This seems to make sense since the ioctl() man page says that the cmd parameter has type int. However, the kernel treats ioctl numbers as unsigned - sys_ioctl() takes an unsigned int, and the macros which generate ioctl numbers expand to unsigned expressions. Furthermore, some ioctls (IOC_READ ioctls on x86 and IOC_WRITE ioctls on powerpc) have bit 31 set, and so would be negative if interpreted as an int. This has the surprising and compile-breaking consequence that in kvm_irqchip_set_irq() where we do: return (s->irqchip_inject_ioctl == KVM_IRQ_LINE) ? 1 : event.status; We will get a "comparison is always false due to limited range of data type" warning from gcc if KVM_IRQ_LINE is one of the bit-31-set ioctls, which it is on powerpc. So, despite the fact that the man page and posix say ioctl numbers are signed, they're actually unsigned. The kernel uses unsigned, the glibc header uses unsigned long, and FreeBSD, NetBSD and OSX also use unsigned long ioctl numbers in the code. Therefore, this patch changes the variable to be unsigned, fixing the compile. Signed-off-by: NDavid Gibson <david@gibson.dropbear.id.au> Signed-off-by: NAlexander Graf <agraf@suse.de>

The pseries "xics" interrupt controller, like most interrupt controllers can support both message (i.e. edge sensitive) interrupts and level sensitive interrupts, but it needs to know which are which. When I implemented the xics emulation for qemu, the only devices we supported were the PAPR virtual IO devices. These devices only use message interrupts, so they were the only ones I implemented in xics. Since then, however, we have added support for PCI devices, which use level sensitive interrupts. It turns out the message interrupt logic still actually works most of the time for these, but there are circumstances where we can lost interrupts due to the incorrect interrupt logic. This patch, therefore, implements the correct xics level-sensitive interrupt logic. The type of the interrupt is set when a device allocates a new xics interrupt.

The sPAPR PCI code defines a PCI device "spapr-pci-host-bridge-pci" which is never used. This came over from the earlier bridge driver we used as a template. Some other bridges appear on their own PCI bus as a device, but that is not true of pSeries bridges, which are pure host to PCI with no visible presence on the PCI side.

For the pseries machine, TCE (IOMMU) tables can either be directly malloc()ed in qemu or, when running on a KVM which supports it, mmap()ed from a KVM ioctl. The latter option is used when available, because it allows the (frequent bottlenext) H_PUT_TCE hypercall to be KVM accelerated. However, even when KVM is persent, TCE acceleration is not always possible. Only KVM HV supports this ioctl(), not KVM PR, or the kernel could run out of contiguous memory to allocate the new table. In this case we need to fall back on the malloc()ed table. When a device is removed, and we need to remove the TCE table, we need to either munmap() or free() the table as appropriate for how it was allocated. The code is supposed to do that, but we buggily fail to initialize the tcet->fd variable in the malloc() case, which is used as a flag to determine which is the right choice. This patch fixes the bug, and cleans up error messages relating to this path while we're at it.

All architectures work the same way, and all check for sas_ss_flags == 0. The powerpc lines are wrong, and do the check the other way round (it's a qemu internal check, which is done wrong only for this architecture, it's more a typo than a bug). It's NOT ppc specific, it's POSIX standard (sigaltstack) and qemu internal. I have a test source that I will send in a follow-up (it's longer than I would have wished, I'm sure that a better test case can be written if needed) Signed-off-by: NAlex Barcelo <abarcelo@ac.upc.edu> Signed-off-by: NAlexander Graf <agraf@suse.de>

The threaded VNC servers messed up with QEMU fd handlers without any kind of locking, and that can cause some nasty race conditions. Using qemu_mutex_lock_iothread() won't work because vnc_dpy_cpy(), which will wait for the current job queue to finish, can be called with the iothread lock held. Instead, we now store the data in a temporary buffer, and use a bottom half to notify the main thread that new data is available. vnc_[un]lock_ouput() is still needed to access VncState members like abort, csock or jobs_buffer.
